Thanks! There's actually 4 resources in the current hud, but only Health is used (the red bar), and very poorly at that. Orb shows cum level, short bar is magic and hearts are a special mechanic. So far it's just placeholder, with the 3rd ecosystem I am diving into these systems. You can expect some of them to get added during smaller updates, but 3rd and 4th major updates are going to fully flesh out the game's mechanics. To give a rough estimate, you're probably looking at ~5 months before the 4th update releases
Edit: nvm, I thought this was Aphrodisiac 2 lol. The last 2 resources were supposed to be used for more exotic penetration and tentacle types. The lil tentacles now just represent hatched eggs, while the hearts I don't even remember if they go up at all. they are both pretty much useless >.<
